1. SIGNAMAX CABLING SYSTEM

2. Signamax Cabling System The Signamax Cabling System Design Principles and Installation Practices are based on the requirements and recommendations of the international and national standards for telecommunications cabling within a commercial building and between buildings in a campus environment. These rules specify cabling topology, transmission media, cabling distances, and telecommunications outlet configurations.

3. Signamax Cabling System Rules given by the Manual are intended to implement a telecommunications cabling designed to support a wide range of different commercial building sites and applications (e.g., voice, data, text, video, and image). Typically, this range includes sites with a geographical extent from 3,000 m (about 10,000 ft), up to 1,000,000 m 2 (about 10,000,000 ft 2 ) of office space, and with a population of up to 50,000 individual users.

5. Cabling Structure Generic telecommunications cabling system structure includes the following subsystems and additional elements: –Horizontal subsystem –Backbone subsystem –Work Area –Telecommunications Room –Equipment Room –Entrance Facility –Administration

6. Functional elements Generic telecommunications cabling system consists of the following functional elements: –Main Cross-connect (MC) –Level I Backbone subsystem cable –Intermediate Cross-connect (IC) –Level II Backbone subsystem cable –Horizontal Cross-connect (HC) –Horizontal subsystem cable –Consolidation Point (CP) –Multiuser Telecommunications Outlet Assembly (MuTOA or MuTO) –Telecommunications Outlet (TO) Groups of these functional elements are connected together to form cabling subsystems.

10. Subsystems Signamax Cabling System schemes consist of three cabling subsystems: –Level I Backbone –Level II Backbone –Horizontal cabling The cabling subsystems are connected together to create a generic cabling structure as shown on the next slide. The cross-connects provide the means to configure the cabling to support different topologies like bus, star and ring.

11. Subsystems

12. Level I Backbone Subsystem The level I Backbone cabling subsystem extends from the Main Cross-connect to the Intermediate Cross-connect(s) usually located in separate buildings.

13. Level I Backbone Subsystem The level I Backbone cabling subsystem includes –the Level I Backbone cables; –jumpers and patch cords in the Main Cross-connect; –the connecting hardware on which the Level I Backbone cables are terminated (at both the Main and Intermediate Cross- connects).

14. Level II Backbone Subsystem The Level II Backbone cabling subsystem extends from Intermediate Cross-connect(s) to the Horizontal Cross- connect(s).

15. Level II Backbone Subsystem The Level II Backbone cabling subsystem includes –the Level II Backbone cables; –jumpers and patch cords in the Intermediate Cross-connect; –the connecting hardware on which the Level II Backbone cables are terminated (at both the Intermediate and Horizontal Cross- connects).

16. Horizontal Subsystem The Horizontal cabling subsystem extends from a Horizontal Cross-connect to the Telecommunications Outlet(s) connected to it.

17. Horizontal Subsystem The Horizontal cabling subsystem includes –the Horizontal subsystem cables –any cross-connections to application specific equipment at Horizontal Cross-connect –the mechanical termination of the Horizontal subsystem cables at the Horizontal Cross-connect including the connecting hardware –the mechanical termination of the Horizontal subsystem cables at the Telecommunications Outlet –a Consolidation Point (optional)

18. Horizontal Subsystem Although Work Area cords and equipment cables are included in a Channel they are not part of the cabling subsystem because they are application specific.

19. Horizontal Subsystem Horizontal cables shall be continuous from the Horizontal Cross-connect to the Telecommunications Outlets unless a Consolidation Point is installed.

20. Interconnection of Subsystems Hierarchical structure

21. Interconnection of Subsystems Cross-connects shall be located in –Telecommunications Rooms –Equipment Rooms –Entrance Facilities

22. Channel & Permanent Link The Channel is the transmission path between active equipment and the terminal equipment. For the purposes of testing, the Channel does not include the mated connection at the IT equipment.

23. Channel & Permanent Link The Permanent Link is the transmission path between the mated connectors located at the ends of the installed cable in a cabling subsystem. The Permanent Link contains the mated connections located at the ends of the installed cabling.

24. Dimensioning & configuring The number and type of subsystems that are part of a generic cabling implementation depends on the geography and size of the campus or building, as well as on the user strategy. Generally there would be –one Main Cross-connect per campus –one Intermediate Cross-connect per building –one Horizontal Cross-connect per floor If the premises have only a single building, which is small enough to be served by a single Horizontal Cross-connect, a level I Backbone cabling subsystem is not required.

25. Dimensioning & configuring There should be at least one Horizontal Cross-connect for every 1,000 m 2 (10,000 ft 2 ) of floor space reserved for offices. If a floor area is over 1,000 m 2 (10,000 ft 2 ), additional Horizontal Cross-connects may be required to provide more effective service to the Work Area.

26. Dimensioning & configuring A minimum of one Horizontal Cross-connect should be provided for every floor. If a floor contains few people (e.g. a lobby), this floor may be served from the Horizontal Cross- connect located on an adjacent floor. If a floor is sparsely populated (e.g. a lobby), it is permissible to serve this floor from the Horizontal Cross-connects located on an adjacent floor.

27. Dimensioning & configuring The functions of multiple cross-connects may be combined.

28. Dimensioning & configuring In some conditions, for example for reasons of security or reliability, redundancy may be built into a cabling design. This might form the basis for the design of generic cabling for a building, providing some protection against such hazards as fire damage or the failure of the public network feeder cable.
